HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Anyone looked into the LFX V6?

Post  SloMo228 on Sun Feb 07, 2016 7:23 pm

I've seen some talk about the LFX but to my knowledge no one has swapped one yet.  There's not a ton of info on this engine out there in terms of dimensions, but from what I can tell it's a bit lighter than an aluminum LS and likely taller and narrower.

Seems like a great engine for a lightweight sports car - good flat torque curve and a 7200 RPM redline.  320-ish HP is more than enough for me.  These are available as pullouts from Camaros for $1500 all day long, and I'm sure you could find one for much less if you watch and wait for a deal.  Of course, the small savings from the cost of the engine could easily be offset by the cost of swapping without a kit and having to one-off everything.  

This is an engine I'd like to stick in my 944, but I'm wary of being the first since I'm certainly no fabrication wizard.  Has anyone looked into this already and have some information to share?  

I've been looking at rebuilding my 944S engine and adding up costs to rebuild it the way I want, for about 230-250hp starts to get up to the rough cost of swapping a much newer motor with 100+ hp more than that.

i remember it being mentioned, but i havent seen anyone doing it.

im just wrapping up my ecotec swap, doing this would be similar in terms of what needs to be done. for my swap the hardest thing was figuring out what parts to start with to then modify to make work. i started with an aftermarket bellhousing for ecotec to t56, then made an adapter from t56 to the torque tube. custom engine mounts were next, and then a custom built oil pan to clear the crossmember. i had to redesign half my cooling system to work properly in a rwd car. clutch was the easy part, 944 disc on the ecotec flywheel.

the lfx would be a similar case. i had a quick look and couldnt find specs, but the bellhousing used with a 3.6l manual trans looks very deep (same issue i ran into with the ecotec). i couldnt find an aftermarket bellhousing for the 3.6l to t56 (t56 bellhousings seem to be the closest to the 944 depth wise). a bonus here is the camaro manual uses the same clutch spline as the 944, you could actually use the entire flywheel and clutch setup from the camaro. the oil pan looks like a rear sump, so thats a great start, but it still looks like itll need some modding. engine mounts should be simple. the rest of it actually looks like it would be pretty simple. i think the difficult part of this swap would be the bellhousing.

You need the detachable bellhousing from the auto. It's shorter and concentric so an adapter is a no brainer....

Good to know. I'd been looking at the manual transmissions and they seemed to have a very deep bellhousing and it didn't look detachable. The good news is the auto transmissions seem to be easier to come by as well.

How deep is "too deep" for the bellhousing? I know there's some wiggle room to be had with different pilot bearings, but I'm sure there's a cutoff where it's a no-go without more serious fabrication.

it depends on a lot of factors. really depends on where the pilot bearing is in relation to the back of the block. if you had a thick flywheel and the pilot bearing was in the flywheel it would allow you to use a deeper bellhousing.

my research with the ecotec and the solstice i found that the asian/warner 5 speed they use had a bellhousing around 7.25" deep. the camaro v6 uses an ay6 made by asian/warner, and the pics look like the bellhousing is the same depth.
